[SPARK-33685][SQL] Migrate DROP VIEW command to use UnresolvedView to
resolve the identifier
### What changes were proposed in this pull request?
This PR introduces `UnresolvedView` in the resolution framework to resolve
the identifier.
This PR then migrates `DROP VIEW` to use `UnresolvedView` to resolve the
table/view identifier. This allows consistent resolution rules (temp view
first, etc.) to be applied for both v1/v2 commands. More info about the
consistent resolution rule proposal can be found in
[JIRA](https://issues.apache.org/jira/browse/SPARK-29900) or [proposal
doc](https://docs.google.com/document/d/1hvLjGA8y_W_hhilpngXVub1Ebv8RsMap986nENCFnrg/edit?usp=sharing).
### Why are the changes needed?
To use `UnresolvedView` for view resolution. Note that there is no
resolution behavior change with this PR.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Updated existing tests.
Closes #30636 from imback82/drop_view_v2.
